Abstract
A model with interparticle inharmonic interaction under the Φ4 external potential is studied Making use of the special relation of relevant parameters in the continuous limit it was possible to obtain various nonclassical soliton solutions specifically compact and peaklike solutions The solutions undergo a jump on their first derivatives at some points of the spacetime manifold These analytic solutions were obtained by considering strong restrictions on their velocities and on the jump conditions The energy concentrated in these solutions shows in several cases a discrete spectrum
