    "abstract": "It is shown that hyperspherical harmonics can be represented in a form\ntypical of traditional microscopic cluster models. This allows those\nhyperharmonics that are responsible for long-range behaviour of valence\nnucleons in loosely-bound nuclei to be selected. The hyperspherical cluster\nmodel based on such hyperharmonics is tested for $^5$He using a simplified\ndescription of the $^4$He core and two versions of the Volkov potential which\ngive $^5$He as either bound or unbound. The study has confirmed that it is\npossible to get a converged solution for binding energy, r.m.s. radius, overlap\nintegral and asymptotic normalization coefficient with small number of basis\nfunctions for bound $^5$He. The values obtained of these quantities are very\nclose to those calculated in a microscopic cluster model.",
