  1. Nuclear Surface Unveiled by Knockout Reactions. Arun K Jain Nuclear Physics Division, B.A.R.C., Mumbai.

  2. N-N Interaction has a complicated nature ( provided to it by the strong coupling finite mass mesons), it has strong short range repulsion (almost a hard core of ~ 0.5 to 0.6 fm) and a finite short range, but a comparatively longer range, ~2 fm strong attraction. r This longer range residual interaction leads to clustering VNN For structure most of the N-N interaction leads to the mean field of finite range Woods Saxon type. rNA VNA Clustering due to long range residual interaction

  3. Knockout Reaction Kinematics p1 p0 q1 q2 pB p2

  4. Knockout Reaction A(a, a’b)B a’ a Incident momentum k1 b

  5. If b were free then k3 = - k3 = 0 E1=E’1+E’2 If the particle is bound by a few MeV, then E0=E’1+E’2+Q as the Q is (- ve) E’1 and E’2are< E1 and E2 respectively. Hence k’1 and k’2 are< k1 and k2 respectively. and θ1 and θ2 of k’1 and k’2 will be slightly < that of free scattering.
