Calcium-48 is used to produce heavy elements. A research facility uses a particle accelerator that can accelerate a proton to 50 MeV to fire a beam of calcium ions at a target. 1) What is the heaviest stable isotope that the ions in the beam could fuse with? 2) Assuming the two nuclei fuse; what isotope is formed in this reaction? 3) Consider this same system with the isotope Calcium-40 instead. What isotope would the fusion produce? 4) Why is Calcium-48 used for this purpose?
A certain isotope decays by beta-decay with half-life of 24.11 days. One of the products is protactinium-234, 234Pa. A.) What is the isotope that decays to make 234Pa? B.)As a result of the decay 0.00025 g of 234Pa has formed. After some time the mass increased to 0.00115 g. How much time in days has passed between the masses
If the mass of one neutron is 1.00866 amu, the mass of one proton is 1.00728 amu, and the mass of a Sulfur-34 nucleus is 33.96786 amu, calculate the binding energy for the 345 nucleus. A) 1.44 x 1010 kJ/mol C) 4.57 × 109 kJ/mol B) 7.53 x 109 kJ/mol D) 2.74 x 1010 kJ/mol
[References] The half-life of carbon-14 is 5730 years. The wrapping of an Egyptian mummy gave off 3.8 counts per minute per gram of carbon. A piece of linen purchased today would give an activity of 15 counts per minute per gram of carbon. How old is the mummy? Jyears old
Calculate the nuclear binding energy (in joules) and the nuclear binding energy per nucleon of: 151 Eu 63 (150.919860 amu) Use 1.008665 amu for the mass of a neutron, 1.007276 amu for the mass of a proton, and 1.007825 amu for the mass of an 1 H 1 atom. (Round each final answer to 4 significant figures.) Enter your answers in scientific notation. ______J_____ J/nucleon
