In this work, the Isoscalar (IS) Giant Dipole Resonance (GDR) and Pygmy Dipole Resonance (PDR) of 92Mo and 100Mo Isotopes were calculated in the farmwork of the self-consistent quasi-particle random phase approximation (QRPA) based on the results of Hartree-Fock-Bardeen, Cooper and Schrieffer (HF-BCS) using 10 Skyrme-type interactions: KDE0v1, eMSL08, SKX, SGOI, v080, SKP, SIV, SIII, SKIII, and SGI. The strength distributions of isoscalar dipole response were compared with the available experimental data. Also, we discussed the statistical relation between the centroid energy and the nuclear matter incompressibility KNM.

En este trabajo se calcularon las resonancias dipolares gigantes (GDR) isoescalares y las resonancias dipolares pigmeas (PDR) de los isótopos 92Mo y 100Mo en el marco de la aproximación de fase aleatoria de cuasipartículas autoconsistente (QRPA) basada en los resultados de Hartree-Fock-Bardeen, Cooper y Schrieffer (HF-BCS) utilizando 10 interacciones de tipo Skyrme: KDE0v1, eMSL08, SKX, SGOI, v080, SKP, SIV, SIII, SKIII y SGI. Se compararon las distribuciones de fuerza de la respuesta dipolar isoescalar con los datos experimentales  disponibles. Además, se discutió la relación estadística entre la energía del centroide y la incompresibilidad de la materia nuclear KNM.
