The quartic anharmonic oscillator – an oscillator-basis expansion approach. II. Study of the wave functions and acceleration of the expansions convergence

For the traditional physical model of the quantum quartic anharmonic oscillator with the Hamiltonian H = ½(p2 + x2) + λx4, which plays a significant role in quantum field theory, elementary particle physics, and nuclear physics, its physical characteristics and properties are comprehensively studied...
