When a lithium-7 nucleus is bombarded by a proton, two alpha particles are produced. The Q value is

A proton is bombarded on a stationary lithium nucleus. As a result of the collision, two alpha -particles are produced. If the direction of motion of the alpha -particles with the initial direction of motion makes an angles cos^-1(1//4) , find the kinetic energy of the striking proton. Given, binding energies per nucleon of Li^7 and He^4 are 5.60 and 7.06 MeV, respectively. (Assume mass of proton ~~ mass of neutron).

When a boron nucleus ( _5^10B ) is bombarded by a neutron, an alpha-particle is emitted. Which nucleus will be formed as a result?

when Boron nuclus (_(3)^(10) B) is bombarded by neudrons , a- particle are emitted . The resulting nucleus is of the elenent …….. And has the mass different ……… are called isotopes .

A deutron is bombarded on ._8 O^16 nucleus and alpha- particle is emitted. The product nucleus is.

Imagine that in any atom about 50% of the space is occupied by the atomic nucleus . If a silver foil is bombarded with alpha - particles , majority of the alpha -particles would :

The ratio of the e/m values of a proton and an alpha -particle is:

Order of q//m ratio of proton, alpha -particle and electron is

When a deuterium is bombarded on ._(8)O^(16) nucleus, an alpha -particle is emitted, then the product nucleus is

In a nuclear reaction, alpha+"_(7)N^(14)toX+p When nitrogen atoms are bombarded by 7.7 Me V alpha- particles, protons are ejected with a kinetic energy of 5.5 MeV . The Q- value of the reaction is -1.26 MeV ( a ) Find the atomic mass of X in amu, identify the element X . ( b ) Find the angle phi between the direction of motion of proton and alpha- particle. Given the atomic mass of "_(1)H^(1)=1.00814 a.m.u. , atomic mass of "_(7)N^(14)=14.00752 amu , and atomic mass of "_(2)He^(4)=4.0038 a.m.u.
