Q3: "The sign of the quadrupole moment changes from plus to minus as the nucleon number goes through closed shell" (a) explain this effect on Li, 10, and Al nuclei. where <2>1/2 = 2.41, 2.66, 2.06 fm, respectively. Show the experimental values of the quadrupole moments for [Li=-0.04, 0=-0.026, Al=+ 0.15] and its calculated values in Schmidt diagram then discuss your results. "Ta

(a) Calculate the radius of 58Ni, one of the most tightly bound stable nuclei. (b) What is the ratio of the radius of 58Ni to that at 258Ha, one of the largest nuclei ever made? Note that the radius of the largest nucleus is still much smaller than ?le size of an atom.

To obtain the most precise value of BE from the equation BE=[ZM(1H)+Nmn]c2m(AX)c2, we should take into account the binding energy of the electrons in the neutral atoms. Will doing this produce a larger or smaller value for BE? Why is this effect usually negligible?

For the {photons} of the following energies, indicate which of the three types of interaction is dominant. You will have to find the Z of each element and use the appropriate figure. a) 1 MeV on Alb) 100 keV in Fed) 10 MeV at P

15. The nucleus 24Mg has a 2* first excited state at 1.369 MeV and a 4+ second excited state at 4.123 MeV. The 2* state has a magnetic dipole moment of 1.02 uN and an electric quadrupole moment of -0.27 b. Which model would be most likely to provide an accurate description of these states? Justify your choice by calculating parameters appropriate to your choice of model.

The wave function for a Hydrogen atom, at time t = 0 is: = V(21,0,0) + 12,1,0) + v?[2, 1, 1) + v3 |2,1, –1). |亚) considering that the notation is n,l, mi). If spin and radioactive transitions are ignored. a) Calculate the expectation value. b) Calculate the wave function at arbitrary time t. c) What is the probability of finding the system in the state with I = 1 and m = 1, as a function of time? d) What is the probability of finding the electron at a distance of 10 ^ -10cm. of the proton? (at t = 0).

Question 3 The nuclear radii of aluminum and gold are approximately r = 3.6 fm and 7.0 fm, respectively. The radii of protons and alpha particles are 1.3 fm and 2.6 fm, respectively. In both (a) and (b), perform the calculation for aluminum and for gold. a) What energy a particles would be needed in head-on collisions for the nuclear surfaces to just touch? (This is about where the nuclear force becomes effective.) Answer b) What energy protons would be needed? Answer

I did my homework related to radiation damage in materials wrong. Please correct my answers and justify them so I can learn from my miskates.

Because electron is lighter that the nuclei by a factor of 2000 and there are different timescales for nuclear and electron motions, based on Born-Oppenheimer approximation the two motions can be decoupled. Then nuclei may be treated as stationary while electrons move around them. Select one: True False
