Question

A particle P collide inelastically with a singly ionized helium atom which is at rest initially helium atom He^+ is a ground state. After collision particle p found p particle scattered at an angle 90 with respect to initial direction of motion and before emitting of radiation He^+ and a particle p have same kinetic energy . He^+is observed to emit total 6 wavelength representative all positive all positive successive transitions in between excited state to ground state leve

Answer 1

Explanation:

The mass of the short-lived particle, its energy and its momentum are ... the atom 10–10 m and for the dimension of the nucleus 10 ... The kinetic energy of each of the final- state.
